ChemistryOpen, Volume 14, Issue 5, May 2025.This research was primarily driven by the aim to extract residual encapsulated gold in sulfidic minerals, which would require the dissolution of the mineral. The electrochemical oxidation of pyrite and chalcopyrite in 0.5 M nitric acid was investigated here, using cyclic voltammetry and electrochemical impedance spectroscopy, to see if there are any ...

C-di-GMP Pathway in Biomining Bacteria
Advanced Materials Research, 2009 Acidithiobacillus ferrooxidans, A. thiooxidans, and A. caldus are acidophilic Gram-negative -proteobacteria involved in the bioleaching of metal sulfides. Bacterial attachment to mineral surface and biofilm development play a pivotal role in this process.

BioMine-DB: A database for metazoan biomineralization proteins [PDF]
, 2016 Biomineralization is the process by which living organisms construct hard skeletons creating complex structures that range from specialized tissues such as bone or teeth to ecosystems such as coral reefs. Biominerals are composed of both inorganic minerals and proteins, which give them extra hardness and special attributes.
